After measuring child's feet, we recommend adding about 3/8 inches (or 1 CM) to the feet's length for child's foot development. For example, some 7 months old baby girls are still in size 2. Some 18 months old boys wear size 5 to 6 already. ?Another way to figure out the shoes size is by measuring the bottom of your kid's current shoes, its Sole length. You can measure it from top to end of the shoe sole and compare with my Chart. Refer to the Insole length column. Then pick the size based on how much growing room you'd like to add.
